I agree with Alexander. The only drawback I see is that after addition
of new dictionaries, there will be 3 dictionaries for each language: old
one, stop-word filter for the language, and stemmer dictionary.

Also, the new approach will solve ambiguity in case of 'simple'
dictionary. Currently, it filters stop-words for the language, which
was selected during DB initialization.
